I am readying myself for a speedy move and am selling various objects.
The object I am listing here would be ideal for a cat owner living in an apartment.
When I had cats, I had a container made for keeping a litter box out on a veranda. It is just a wooden box open at one end, just the right size to accommodate a standard-sized cat litter box, with a piece of a wood attached near the open end to serve as a wedge so that the litter box sits firmly inside. It has a rainproof roof. It is high enough for a large adult cat to enter through the open space and attend to its bodily functions in comfort and privacy. It served my two cats well for many years until their demise. In fact, I used to keep two litter boxes going and I know that the outside enclosed box was their favourite because the box there was always fuller.
I can part with this item, which is probably unique, for thirty euros. It would cost at least four times this to have a carpenter make it.
